Fixed dialogs on rotate and duplicate reconnect item.

Dialogs will no longer re-appear after being closed after you rotate the
screen.

Added a confirm-quit dialog. Quitting games is now properly relayed to
the server. The cookie will be cleared if you explicitly press "Leave
game" or the Back button followed by "Ok" on the confirm-quit dialog.
Leaving a game by way of the home button or by opening another task is
not treated as quitting the game.

Made the lost connection dialog not allow closing by tapping in background.

Fixed a bug where the reconnect item on the game list was being
duplicated when you rotate the screen.

The trade add proposal dialog sequence now shows more information about
players and estates. Players become their piece color and estates become
their gradient color. In money trades, players list their current money
total. In estate trades, estates list their current owner and players
list their current number of owned estates.

All files have been converted to Unix EOL and always end with an EOL.

Pieces now move one space at a time, since the animated movement has
been really buggy. Pieces' current location is now live in the Player Overlay.

Many more bug fixes.
